The Edge142 is a 4 X 2 cross point switch with output
edge deskew capability. Manufactured in a high
performance bipolar process, it is designed primarily for
channel deskew applications in VLSI and Mixed-Signal
test equipment.
Any of the four input signals may be selected as the
source for either output. The 142 performs test head
multiplexing, adjacent channel multiplexing, and signal
buffering for both the drive and receive signals, in addition
to timing deskew.
The delay value (and resolution) is controlled via an
external voltage DAC. The delay element is designed
specifically to be monotonic and very stable while
delaying a very narrow pulse over a limited delay range.
The part offers separate delays for rising vs. falling edges.
The rising edge delay range is 1.5 ns and the falling
edge adjustment range is 300 ps.
The Edge142 is also well suited for 1:2 or 1:4 signal
fanout applications that require:
- multiple signal sources
- output enable / disable
- timing deskew on the output
